SELF-CLEARING BREAKING-PLOW COLTER.

SPECIFICATION forming part of Letters Patent No. 340,281, dated April 20, 1886.

I Application filed September 4, I835. Serial N0.176,131. (No model.)

To all whom it may concern.-

Be it known that I, BENJAMIN CRAIYDALL BROWNELL, of Centre Junction, in the county of Jones and State of Iowa, have invented a new and Improved Self-Clearing Breaking Plow Oolter, of which the following is a full, clear, and exact description.

My invention relates to improvements in plow-colters; and it consists in the peculiar construction and arrangement of parts, as here inafter fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of a breaking-plow with my colter-clearing attachment applied thereto. Fig. 2 is a plan view of the same; and Fig. 3 is a view similar to-Fig, 1, except that the clearing-roller is shown in section.

A represents the beam, B B the-handles, and A the mold-board, of the plow. The colter-standard O is secured to the beam A in the ordinary manner, and at its lower end is welded to the colter D. A spindle-likeroller, E, formed with an outwardly-flaring top, a, is mounted on a rod, 1), the lowerend of which rides in a socket formed in the upper part of the colterD, the top of the rod being carried backward and held in place by the strip a, which is held against the beam A by the clips (I (I, so that the roller E is mounted at an angle which is a practical con tinuation of that given to the colterD. The lower end of the roller E is protected by a shield, F, which is firmly riveted to the coltor D.

In order that the roller may be moved to or from the colter, the barb is threaded and carries two adjusting-nuts, i z, whichalso serve as washers and define the position of the roller upon the bar, being moved up or down, as thecircumstances of the case require.

When the plow to which my self-clearing attachment is secured is in operation, any hazel-brush, weeds, grass, or other obstruct ing material caught by the colter will, on account of the incline given thereto, rise above the colter and shield F until it rests upon the roller E, a further rise being prevented by the flaring top a. structin g material has risen so as to rest against the roller E, it is likely to be caught upon one side or the other, and when so caught a very slight pull willcause the roller to revolve and discharge itself.

Having thus described my invention, what I Patent, isi 1. The combination, with a colter, of a bar held above the same, and a vertically-adjustable roller thereon, substantially as described.

2. The combination, with a plowbeam, a standard secured thereto, and a colter on the lower end ofsaid standard, of a bar secured to the beam and colter in an inclined position in front of the colter-standard, and a vertically-adjustable roller on said bar, substantially as herein shown and described.

3. The combination, with a plow-beam and colter, of a threadcd rod secured to the beam and colter, a roller on said rod, and nuts above and below the roller, for adjustably securing the same on the rod, substantially as herein shown and described.

4. The combination, with the beam A, the standard C, and the colter D, provided with the shield F, of the threaded rod 1), the roller stantiall y as herein shown and described.
